SUPPLY-TANK FOR WATER-CLOSETS.

SPECIFICATION forming part of Letters Patent No. 329,361, dated October 27,1885.

T 0 to whom it may concern.-

Be it known that I, WILLIAM BUNTING, J r., of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Supply-Tanks for ater-Closets; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this application.

My invention relates to that kind of watercloset supply-tank apparatus in which the mechanism is operated by the action of the water-closet seat, and in which there is produced both a preliminary wash and an after-flush, and my invention has for its main objects to provide for use in this kind of water-closet apparatus means or mechanism which, while simple and efficient in construction and mode of operation, will perfectly produce the desired results of a preliminary flush or wash and an after-wash, in the proper and desired proportions as to the quantity of water employed at each flushing operation.

To these main ends and objects my invention consists in the novel devices and combination of devices which will be hereinafter more fully described, and more particularly pointed out and defined in the claims of this specification.

To enable those skilled in the art to make and use my invention, I will now proceed to describe the same, referring by letters of reference to the accompanying drawings, which form part of this specification, and in which I have illustrated my invention carried out in that form which is the best now known to me, and in which I have so far successfully practiced my improvement.

In the drawings, Figure 1 is a top view ofa supply-tank apparatus made according to'my invention. Fig. 2 is a vertical longitudinal section ofthe same,taken at the line x 00 of Fig.1. Fig. 3 is a partial vertical section taken at the line y 3 Fig. 1, and representing the parts in that position in which they would be when the operating-lever shall have been nearly pulled down by the depression of the closetseat. Fig. 4 is a similar section on the line y 3/ of Fig. 1, but with the parts in the positions in which they would be when the operatinglever is rising, as it does immediately upon the releasement from occupancy of the seat of the closet.

In the several figures the same part will be 5 5 found designated by the same letter of reference.

A is the tank,of the usual construction, and provided with a ball supply-cock, B, connected, as usual, with a supply-pipe, O, and 6 provided with the ordinarylever, D, and float E, for closing the supply-cock whenever the tank shall have become filled to the proper extent.

F is the exit-pipe or discharge-nozzle of the 6 5 tank,from which a pipe leads, as usual, to the bowl of the closet, and which is connected with the ordinary valve-chamber, G, with which is combined a valve, H, that is lifted and allowed to descend by gravity in a wellknown manner, said valve being suspended by a rod, I, from the lifting mechanism, which latter will be presently described.

J is a siphon,(of the usual construction and arrangement,) the longer arm of which commu- 7 nicates with the valve-chamber, and through it with the discharge or exit nozzle of the tank. Said siphon is, however, supplied with an airinduction pipe, K, which, as shown, extends from a point near the upper end of the shorter leg of the siphon to a point where it opens upwardly immediately beneath the weighted end of the operating-lever L, which latter is formed or provided with a valvular packing device, a, that at certain times, as 8 will be hereinafter explained, closes up the open end of said air-pipe K. The lever L is mounted in about the usual way, so that its pivotal axis M will turn freely in suitable bearingboxes at N, and said axis M is formed or provided, as shown, with a radially-pro jecting arm or lug, b, which operates to depress the shorter arm of a rocking lever, c, that is pivoted, as shown, in suitable earpieces, (I, permanently arranged for the pur- 5 ose. p O is the valve-lifting lcver,which is pivoted at one of its ends in cars e, and which has connected with it in a flexible manner the upper end of the valve-rod I. O is lifted at different times by two different means or devices, as follows: Every time the This valve-lever 10o longer arm of the operating-lever L is pulled down by the depression of the seat of the closet the free end of the valve-lever O is lifted by the upward stroke of the longer arm of the rocking lever c. The latter, afterhaving lifted the valve-lever, passes clear of the latter. allowing the latter to fall and the valve H to seat itself by gravity, while at each ascent of the longer arm of the lever L a laterally-projecting lug, f, on the inner side of the lever comes into contact with an eccentrically-pivoted block on one side of the valve-lever O,and, pressing upwardly against said eccentricallypivoted block, carries up the valve-lever, to which it is attached, thus again lifting the valve. As the ascending arm of the valve reaches its highest point, however, the pivoted block 9 turns on its axis in such manner as to become released from contact with the lever-lu g f, and permit the valve-lever to again descend,so that the supply-valve may be again closed. It will be seen that during each complete movement of the main lever Lthat is, each time said lever is pulled down by the descent of the closet-seat and allowed to reascend to its original position by the ascent of said seatthe valve H is lifted and allowed to fall by reason of the action of the rocking lever c, and is again lifted and allowed to fall through the action of the lugfon the eccentrically-pivoted block 9 of the valve-lifting lever, the rockingleverc beingpermitted at each ascent of the longer arm of the lever Lto resume the position from which it was moved when said longer arm of said lever L previously descended. It will also be seen that whenever the longer arm of the lever Lis pulled down, for the purpose of lifting the valve H, the outer end of the air-pipe K is opened and leftopen, so that the siphon J cannot act to empty the contents of the tank through the valve-chamber, and so that all the water which can pass from the tank will be such in quantity as can enter the valve-chamber during the short time that the valve H is off of its seat, which quantity of Water will be comparatively small, but sufficient for what is called a preliminary wash to the bowl. Every time, however, that the valve H is lifted by the ascending movement of the longer arm of the lever'L the open or valvular end of the air-pipe K is closed by the packing device or valve a about at the same time that the valve H is seated, or immediately afterward, so that the siphon may act in the usual manner, and continue to supply the valve-chamber G with water until the contents of the tank, down to the level of the lower end of the shorter leg of the siphon, shall have been exhausted. It will be understood that by varying the elevation or location at which the inner end of the air-pipe K communicates with the siphon (so as to have this point ofcommunication more or less below the level of the water in the tank) the amount of water discharged through the valve-chamber at each preliminary wash may be regulated or predetermined as may be desired. Of course vevery time the contents of the tank is discharged the ball-float E drops, as usual, and the ball-cock is opened and resupplies the tank up'to the level at which the ball or float will have to ascend to effect the reclosing of the cock or faucet B. The e'ccentrically-pivoted block 9 offers no impediment to the descent of the lug f when the longer arm of the main lever L is pulled down to effect the preliminary flush, but simply swingsvery slightly at its pivotal connection, so that while the block ascends bodily and the lug f descends bodily said block and said lug will freely pass by each other. When, however, (after the use of the closet,) the longer end of the lever L is allowed to ascend, the lug f, coming against one of the under inclined faces of the block 9, engages itself with said block in such a manner that the lug and the block are obliged to travel upwardly together-with little or no relative movement until these devices are nearing the end of their upward movements,when said block 9 will turn (considerably) on its pivot until the lug f and block 9 become dis= engaged, to permit the descent of the valvelever,and the consequent fall by gravity of the valve Hpnto its seat.

Of course the precise forms shown of the block 9 and lug f are not indispensably necessary to the mode of operation hereinbefore explained, and the shapes and sizes of other parts of the contrivance, herein shown and described, may be more or less varied without changing its principle of construction or mode of operation.

It will be seen that by the combinatiomwith the valve-lifting lever O, of the rocking'lever 0, operated by the arm or lug projecting from the axis of the main lever, and the eccentrically-turning block 9, operated upon, as described, by thelugf, projecting from the main lever, a very simple, strong, durable, and efficient contrivance is provided for use, by means of which, through the simple descending and ascending strokes of the longer arm of the lever L, the tank-valve will be properly operated to produce the necessary preliminary flush and after-wash in the water-closet bowl.

Having now so fully explained the construction and operation of my improved watercloset snpplytank apparatus that those skilled in the art can readily make and use my improvements, what I claim as new, and desire to secure by Letters Patent, is

In combination with the valve-lifting lever O, pivoted at one end to afixed fulcrum, and a rocking lever, c, similarly pivoted, an arm or lug, b, on the axis of the main lever L, arranged and operating to throw up the longer arm of the lever c (to elevate the free end of the valve-lever) at each downward movement of the main lever L, as described, and means, substantially such as described, for effecting the lifting of the free end of said valvelever at ICQ each upward movement of the longer arm of which is removed from and reseated on the the main lever L, all substantially in the man exposed end of said air-pipe by the said lever ner and for the purposes set forth.
